I am really curious what these two youngsters are. Photos will tell for sure.
Cockerels?
Keep in mind that some people who can’t have or don’t want cockerels , hope to give them a live elsewhere without the trouble of rehoming them.
Do you want to keep cockerels?
Pullets?
Maybe a wonderful unexpected gift from a farmer nearby? Make a coop with a closed run, rebuild (part of) a shed or buy a coop with run meant for at least 6 chickens (spacewise). Catch them in the dark. And lock them in for at least a few weeks before you free range them.
